Why is Auguste Rodin considered important in the development of modern sculpture?

Auguste Rodin is considered a pivotal figure in the development of modern sculpture because he rejected rigid academic traditions, instead using sculpture as a deeply expressive medium. His influence was revolutionary in several key ways:1

• Innovative Modeling: Drawing inspiration from Honoré Daumier, Rodin utilized bold, emotive surface modeling rather than literal representation. He often left his works in a state of "becoming," avoiding the definitive, polished finish typical of earlier sculpture.1
• Integration with Space: Unlike traditional sculpture, which relied on the interplay of solid mass and void, Rodin’s work was "explosively opened," allowing his figures to fuse with the surrounding space.1
• Expanded Composition: He significantly broadened the range of sculptural subjects, famously working with fragments like broken torsos and creating unconventional, expressive gestures that captured the movements of modern life.1
• Revival of the Medium: By focusing on subjective effects and emotional intensity—seen in works like The Gates of Hell—Rodin restored prestige to sculpture, profoundly influencing the generation of European sculptors who followed him.1
